In contrast, fueleconomy actually increased by 15% during that period. Tags: Fuel Efficiency. Knittel, 2009. Click to enlarge. Knittel, Christopher R.
An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fueleconomy standard policies by up to 60%.
Worldwide, the vehicle fleet is not making enough progress on fueleconomy and is failing to reach global targets aimed at reducing CO 2 emissions, cutting oil consumption and improving energy efficiency according to a new report from the Global FuelEconomy Initiative (GFEI) ( earlier post ) released at the Paris COP21 Climate Summit.
Vehicle size, a key determinant of fueleconomy, has shown a reduction in OECD countries, while the non-OECD trend is toward bigger vehicles. The analysis, an update of an earlier work using data from 2010 and 2011, found that the global average for light-duty vehicle fueleconomy was 7.2 Source: GFEI. Click to enlarge.

However, increased dilution leads to increased combustion instability resulting in reduced fuel-economy benefits. Davis (UC Davis), R.Sankaran (ORNL). Some strategies to reduce emissions include running the engine highly dilute, with excess air or with recirculated exhaust gases as part of the combustion charge.
The duty cycle typically associated with these vehicles takes advantage of the fuel saving and emission reduction features of the hybrid system. —Scott Davis, manager for Eaton’s Hybrid Power business unit in North America. The system recovers energy normally lost during braking and stores the energy in batteries.
